command line partition information

[Joaquin Luna]

Hello Linux powerpc community,

 

I am trying to move from 2.6.20 kernel to the new 2.6.27.4 kernel.  I am
not finding my root file system partition with the new kernel.  I am not
sure if I need to change my dts file, or if the problem is some where in
my kernel config.  In either case, it is evident from the boot log that
my partition table is not being used.  Where it says "[    0.917162]
List of all partitions:" it just lists the entire size of my flash, and
none of the partitions listed in the command line.

I do not list any partitions in my dts file, though I tried and not seen
any change in the behavior.  I have enabled the option in the kernel to
parse the partition information from the kernel command line, is there
something else I need to do to set up the mtdblockX devices?

 

Boot Command:

 

mtdparts=mtdparts=nand0:2m(u-boot),3M(kernel),128K(dtb),30M(jffs2),32M(m
ycust),90M(myfs),90M(myfs2)

mtd_args=setenv bootargs root=/dev/mtdblock3 rw rootfstype=jffs2
$mtdparts console=ttyS1,115200

 

Boot Log:

Thanks to all who can help,
